由南昌矿山机械研究所设计,江苏兴化矿山机械厂生产的机械化露天矿山装药设备——BC型露天矿装药车,能独立完成铵油炸药的运输、现场混制和装填等工作,在我国大、中型露天矿山应用广泛。使用中发现,该装药车螺旋输送装置计量系统不能直观显示,存在操作不方便、装药精度低和误差较大等缺陷。 Designed by Nanchang Mining Machinery Research Institute, the mechanized open pit mining equipment -BC type open-cast mining truck manufactured by Jiangsu Xinghua Mining Machinery Factory can independently carry out the transportation, site mixing and filling of ammonium oil explosives, China’s large and medium-sized open pit mine is widely used. During use, it is found that the metering system of the screw conveyor of the medicine truck can not be directly displayed, and the operation is inconvenient, the charging accuracy is low and the error is larger.
